AEM Failsafe Wideband + boost/vacume + 3 Hr data logger

[hwmech]

Anyone ever seen these? Im shopping around for a wideband setup for when i start running spray and I found this, it also has parameters you can setup in the software to where you can make it shut stuff off or turn on anything when your boost or A/F ratio hit a limit you set.

So I am thinking I can set a switch up for when I spray if the a/f ratio goes wrong for what ever reason I.E. fuel pump for the wet kit stops working and its just spraying a huge dry shot the AEM failsafe will shut the Zex kit down and save my engine.

just wondering if anyone has seen or used these
